when using expanding foam can it be put straight onto the glass

Yes. Some people feel it works better if you have a little silicone on the glass to help it adhere, but others attach it directly to the glass.

The silicone, if spread nicely looks a lot better than seeing the foam, but if it is going on a back that will not be seen it is not that important.

So what do you used a colored silicone? Not like clear aquarium silicone....right?

I used the GE black II silicone, to coat the back of the tank, and to coat the front of the foam, along with the dirt mixture. Black hides pretty well with the coco bedding.

I used GE II silicone in brown, but black or bronze also seem to work well. Like Superfly I also used it on top of the foam after it dried to bond coco bedding to the foam. Make sure the coco bedding is dry, or it will not stick well.

I wouldn't recommend putting the foat right on glass. In my case few years later it detached. It holds on well on my acrylic tanks though. I did score the plexi first before I put the foam on.

Im crossing my fingers you are wrong Marty, thats my Orchidarium your talking about. hehe. I didn't put in any silicone on that one.
If you use great stuff, black silicone will also help blot out the white of the silicone. I would put some silicone on the sides as well incase you get any great stuff on the side glass by accident. Infact, you probably will, as your background will be too thick to not go on the side glass. Just the nature of what we are trying to do when we make backgrounds.

so can this expanding foam be used for sculpturing a landscape in a viv, also can you use this in an aquarium?

Yes, you can use the foam to sculpt a landscape. I don't know if you can use it underwater, but Im willing to bet you can, as I have seen cans of this stuff for sale in tropical fish stores.

yes for aquariums. The foam cures non toxic and water proof. it can be porus though so watch for holes algie can grow in.
